STYLOGRAPHIC FOUNTAIN-PEN. l l

SPECIFICATION forming part of Letters Patent No. 233,616, dated October26, 1880.

Application filed September 17, 1880. (No model.)

To all 'whom it may concern Be it known that I, JOHN C. HARING, ofJersey City,i'n the county of Hudson and State of New Jersey, haveinvented a new and Improved Stylographic Fountain-Pen, of which thefollowing is a specilication.

My invention relates to stylographic fountain-pens in which an air-tubeis arranged inside of a sectional pen-case and air is admitted into thetube through one side of the case and expelled into the ink-chamber forthe purpose of causing ink to flow freely from the writing-point duringthe act of writing.

The objects of my invention are, iirst, to dispense with the shortinlet-tube heretofore used for establishing an air communication betweenthe outside of the pen-case and the internal air-tube, and to fit theair-tube tightly into a section of the pen-case and introduce air intothis airtube through holes made through the latter and through saidsection second, to construct the case of a stylographic `fountain-pen ofthree sections, the intermediate connecting section of which isperforated at right angles to its length and interiorly grooved in thedirection of its length, which latter section is adapted to have fittedinto it and to hold in place an air-tube 5 third, to combine a needleand needle-spring adjuster with a non-extensible but axially-adjustableair-tube, which receives air through its side and through the side ofthe section of the pencase into which the air-tube is fitted. I attainthese objects by mechanism illustrated in the accompanying drawings, inWhich- Figure 1 is a diametrical section taken through my improved pen,highly magnified. Fig. 2 is a cross-section through Fig. l in the planeindicated by dotted line at' Fig. 3 is an enlarged diametrical sectionthrough the air-tube, having a perforated and split collar applied onit. Fig. 4t is a cross-section through Fig. 3, taken in the planeindicated by dotted line y y thereon.

Similar letters refer to similar parts throughout the several views.

A designates a short tubular section of the pen-case, which is theintermediate connecting section of the barrel B and point-section C, asshown in Fig. 1. This section A, which is adapted to receive differentstyles of barrels and point-sections, is constructed with male screws cc', a perforation, et, and with one or more grooves, b. The perforationa, is `at right angles to the longitudinal axis of the section A, andthe groove b is formed in the interior of this section in adirectionwith the length thereof.

D designates an air-tube, to which is applied the needle d and itsspring and a stopple or plug, c. This air-tube is of such a diameterthat it will tightly fit into the screwsection A, as shown in Fig. l,and when properly adjusted therein a hole, c', registers with the holec, and thus forms a conduit for admitting external 'air directly intothe airtube D, without the use of a tube separately formed for thispurpose. The groove b forms a conduit for the ink to iiow from thebarrel B into the point-section.

It will be seen that the air-tube D is iitted in contact With thescrew-section A, and that the admission of airinto the air-tube isthrough the holes ct a. The air-tube is also, by this means, properlycentered and iirmly held in the pen-case or the section A thereof. Theindependent air-tube-holding section A` admits the use of differentkinds or styles of barrels and point-sections, as fancy may dictate.

In practice the hole a through the air-tube may be made larger than thehole c through the screw-section A, for the purpose of facilitating theproper adjustment of the two holes a a with respect to one another.

It' desired, my construction will allow the inlet-conduit a c to beregulated in size or entirely closed by simply adjusting tube D aboutits axis in section A.

It" desired, a grooved enlargement may be formed on the air-tube D, or agrooved or split collar may be applied on the air-tube, which wouldrender unnecessary making the bore of the screw-section Aas smallproportionally'as shown in Fig. 1.

Figs. 3 and 4 show an enlargement on the air-tube, formed by the use ofa lon gitudinallysplit collar.

The air which is admitted into the air-tube D is expelled into thepoint-section C through the lower end of said tube, as shown in Fig. 1.

The needle d is iixedto a needle-rod, f,

roo

which has an oblong slot, g, through its upper end, and through thishole passes a pin, h, that loosely attaches the needle-rod to the pluge, that closes the upper end of the air-tube D.

A screw-threadedr collar, fi, is rigidly fixed on the needle-rod f nearits upper end, the threads of which collar receive the coils of atension-spring, s, which bears upward against the lower end of the pluge. B v turning the spring s about its screw-collar 'i the former can bemore or less compressed above the collar, and thus the tension can benicely adjusted.

I do not claim the hollow handle of a stylographic fountain-pen formedof the three sections A B G, as I am not the tirstinventor thereof;neither do I claim other features herein shown which are notspecifically set forth as my invention.

WhatI claim as niy invention isl. The screw-section A, perforated at aand `erooved at b, in combination with the air-tube D, perforated at a',substantially as described.

2. In a stylographic fountain-pen, the airtube D, fitted tightly intothe screw-section A, provided with the air-ducts a a and ink-duct b,substantially as described.

3. rIlhe ease for a stylographic fountain-pen, formed of the barrel B,point-section C, and an intermediate screw-section, A, perforated andgrooved for the purpose described.

4. The needle-rod f, loosely connected to the plug,` e, in combinationwith the screw-collar t' and spring s, substantially as described.
